PARTNERSHIP CONSISTING- OF EDWARD GESSER, IBARN'EY NEHLS, FRANK SHIELDS, AND CARL IB. NEHLS.

Beit known that L'CARL B. NEHLs, a citi- Zen of the Unitedstates of America, residthem upon coarse work until they. become ing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain new and useful Improvements in Buiiing or. Polishing Wheels, of which the following is a specification, .reference being had therein to the accompanying drawings l The invention-relatest'o bufling or polishing whe'els,pand it is the primary object of the invention to obtain amore-resilient construction in which (the work can be per-v formed with less fatigue vto' the operator.

To this end the inventioncomprises the` novel construction as hereinafter set forth.

In the drawings: Figure 1 is a' section through the wheel in the aziial plane thereof Figs. 2 and 3 are side elevations of two of the disks inclosing the wheel; and Fig. 4 is a similar view showing a modied construction. Y

My improvement',y belongs to buiing or polishing .wheels of the type in which a series of disks formedof rags or other fabric are glued` together and are peripherally sized and coated with the abrasive material. In the use of such wheels it has been found that when'first made they are not adaptedfor ne work, so that it is customary tolfirstruse more yielding. Furthermore, on account of the rigid character ofthe Wheels, the work performed thereon is more fatiguing to the operator. With my improved construction the initial rigidity of the wheel is overcome,l

.wheel while the cut-away members vinrapartnv and furthmore a greater degree of resiliency- `is imparted theretothan with constructions heretofore used.

Broadly described, my improvement com -l prises the cutting away of portionsl of .the

disks soI as to lessen the rigidity thereof.

Preferably the disks.v are alternately vpartially cut away. and left imperforate, the imperforate members retaining the form of the the yielding character. Thu's,- as shown in BUFFING 0R POLISHING WHEEL.

a, 191s. serial No. 49,705.

Fig. 1, A A, etc., are imperforate disks, and 4interme'dlate these disks are partially cutaway dlsks B B etc. The disks maybe cutaway centrally, as indicated at C, Fig. 3 or 1n segments-D or a series of 1apertures E, as shown 1n Fig. 4. In each case the rigidity of the structure is lessened and the resiliency d increased.

In assembling the parts they may be mounted upon an arbor or shaft F and secured by gluing and by clamping collars G, as shown 1n Fig. 1. The peripheral portions of the disks are then sized and coated with the abrasive material, after which'they are,

in condition for use.

In operation it has been-found that wheels constructed in the manner above described Amay at once be used upon fine Work vand on account of their resilient nature lessen the fatigue to the operator.

'The disks may be formed of. any suitable material securedby a spiral line of stitching II, as shown in Fig. 2.' A

What I claim as my invention is:

-1. A buiing-wheel, comprising la body formed of a series of fabric disks of substan tially uniform diameter, ,forming a continuous cylindrical surface, portions of said such as rags with fabric facings,

disks being cut-away to increase the resiliency.

2. A buliing-wheel, comprising a series of fabric disks alternately imperforate and `partially cut-away, and forming a continuous cylindrical surface.

3. A buing-wheel, comprising a body formed of a series of'fabric disks forming a contmuous cylindrical surface, the periph-- eral portions of all of said disks being imperforate, and portions .of alternate disks withinthe periphery being cut-away.

In testimony'whereof I aflix my signature in presence of two witnesses.
